J Wynia has created a screencast (.wmv) showing how he reads and manages his RSS. From what I can see, he's a RSS überuser.

"I couple of weeks ago, Alex Barnett was listing the things that he considered requirements for a good RSS reader. It appeared to me that he’d overlooked what I use as my solution: Thunderbird, a dedicated IMAP account and my OPML file run through some custom scripts (though there are plenty of RSS to email services as well). He asked if I could do a quick screencast, showing a little more about how I work. So, a couple of days ago, I did just that."
